you just added.
2. Select the Use the following IP address option. Enter the IP address and network mask of the VLAN interface. If
required, you can also configure the address of the DHCP server for the VLAN by clicking Add.

Configuring a VLAN to Receive a Dynamic Address
In a branch office, you can connect a controller to an uplink switch or server that dynamically assigns IP addresses to
connected devices. For example, the controller can be connected to a DSL or cable modem, or a broadband remote
access server (BRAS). shows a branch office where a controller connects to a cable modem. VLAN 1 has a static IP
address, while VLAN 2 has a dynamic IP address assigned via DHCP or PPPoE from the uplink device.

Configuring Multiple Wired Uplink Interfaces (Active-Standby)
You can assign up to four VLAN interfaces to operate in active-standby topology. An active-standby topology
provides redundancy so that when an active interface fails, the user traffic can failover to the standby interface.
To allow the controller to obtain a dynamic IP address for a VLAN, enable the DHCP or PPPoE client on the
controller for the VLAN.
The following restrictions apply when enabling the DHCP or PPPoE client on the controller:
l You can enable the DHCP/PPPoE client multiple uplink VLAN interfaces (up to four) on the controller; these
VLANs cannot be VLAN 1.
l Only one port in the VLAN can be connected to the modem or uplink switch.
l At least one interface in the VLAN must be in the up state before the DHCP/PPPoE client requests an IP
address from the server.
Enabling the DHCP Client
The DHCP server assigns an IP address for a specified amount of time called a lease. The controller automatically
renews the lease before it expires. When you shut down the VLAN, the DHCP lease is released.
